Topic
 Creating Snow
Chemistry Concept
 Forming snow crystals with varying spray nozzles and observing the variation of the crystals
Hypothesis
 To observe artificial snow making, and to measure the snow type, snow quality, and the amount of snow produced.

Apparatus and Chemicals needed
 Free plan given by Snow at Home

SG T-Type (Internal mix)

SAH_SG_TTypee.jpg

materials needed for build:

  1. ¼” cap - QTY 1
  2. 6” x nipple - QTY 1
  3. ¼” x Tee - QTY 1
  4. ¼” x 90 DEG street elbow - QTY 1
  5. ¼” close nipple - QTY 1
  6. ¼” mini ball valve - QTY 1
  7. 2” x nipple - QTY 1
  8. ¼”female x ½”male bushing - QTY 1
  9. ½”female to Garden - QTY 1
  10. Quick connect air fitting
  11. 7/64 drill bit
  12. One roll of Teflon tape
Procedure
 1. Setup equipment to preform the experiment outside
2. Attach SG T T-Type to the water to post and measure angle.
3. Connect air source and water source.
4.record humidity and air temperature.
5. open valve to start internal mix of air pressure and water.
6. record production time once snow is developing
Safety Information and Chemicals needed
 We will need a water source that with a hose can reach outside. An air compressor or a pressure washer. A microscope with a camera attached to it to capture the snow flakes. A Light absorbing surface that snow flakes can land on. A thermometer and a humidity sensor.
Other Information
 *very Cheap to build
*a great solution for snow-less Minnesota winters
